安卓：从通知的PendingIntent不会把是否回的活动在屏幕上触发的onCreate（） [英] Android: PendingIntent from Notification doesn't trigger the onCreate() if bringing Activity back on Screen

问题描述

想我有一些misunderstandigs意图旗..我想要做的是，我有一个无线流媒体应用，其中有两个活动（PlayerApplication和SettingsScreen）。我有一个流而Service.class在后台运行，它拥有一个通知，以及（你可以停止/通知的覆盖菜单和PlayerApplication开始播放）。如果用户点击该通知，PlayerApplicationActivity应该是COM回到屏幕。

一切工作正常，预计这样的：用户打开SettingsScreenActivity - >打开NotificationOverlayMenu - >点击在通知 - >的PendingIntent恢复到PlayerApplicationActivity

现在，PlayerApplicationScreen是有的，但我无法点击任何东西。我明白了，我PlayerApplication的OnCreate（）不会被触发，如果我从通知中恢复。但布局看起来很好（在OnCreate也充气（））

我使用了Service.class以下的PendingIntent：

 的PendingIntent contentIntent = PendingIntent.getActivity（
      this.getApplicationContext（），//Service.class
      0，
      新的意图（这一点，PlayerApplicationActivity.class）
             .setFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP）
      0）;
 

因此​​，实际上的PendingIntent应该把活动（如果已运行）回到顶端。我使用错误的意图还是我错过了点？

编辑：
和我的Manifest.xml宣布launchMode

 的android：launchMode =singleTask
 

解决方案

我只是想出了什么我做错了：

1. 有关我的目的，我使用了错误的launchMode。正确的是 singleTop 不是 singleTask




2. 我声明在＆LT的launchMode;应用节点＆GT; 而不是＆LT;活动的节点＆GT;

     //的Manifest.xml
   ＆LT;活动
       机器人：名字=...
       机器人：launchMode =singleTop＆GT;
    

guess I'm having some misunderstandigs with the Intent Flags.. What I'm trying to do is, I'm having a radio streaming applications, which has two Activities (PlayerApplication and SettingsScreen). I have a Service.class for Streaming which runs in the background, which holds a Notification as well (you can stop/start playback in the notification-overlay menu and the PlayerApplication). If the User clicks on the Notification, the PlayerApplicationActivity should be com back to screen.

Everything works fine, expect the case: User opens SettingsScreenActivity -> opens NotificationOverlayMenu -> clicks at Notification -> PendingIntent resumes to PlayerApplicationActivity

Now, PlayerApplicationScreen is there, but I cannot click anything. I see, that the onCreate() of my PlayerApplication isn't triggered, if I resume from Notification. But the layout looks fine (also inflated in the onCreate())

I used following PendingIntent in the Service.class:

PendingIntent contentIntent = PendingIntent.getActivity(
      this.getApplicationContext(), //Service.class
      0, 
      new Intent(this,PlayerApplicationActivity.class)
             .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP),
      0);

So actually the PendingIntent should bring the Activity (if already running) back to the top. Am I using wrong Intents or am I missing a point?

EDIT: and I declared launchMode in Manifest.xml

android:launchMode="singleTask"

解决方案

I just figured out what I was doing wrong:

1. For my purpose I used the wrong launchMode. Right one is singleTop not singleTask

2. I declared the launchMode in the <application-node> instead of the <activity-node>

   //Manifest.xml
   <activity
       android:name="..."
       android:launchMode="singleTop" >
